Sacrifice Resulting in a Mere Day’s Delay

Compass Carburettor gently planted the Mutated Blood Vitality Grass on Dullin's corpse, feeling its mutations continue to deepen. But he immediately commanded it to stop absorbing Dullin's essence, "This wouldn't do."

The reason was that this Blood Vitality Grass was his ability. So, he was able to sense its changes clearly. And now that he had the Origin Art of Divine Sense, he was able to gain a clearer understanding.

It was the fact that absorbing Dullin's body wasn't enough to fully mutate the Blood Vitality Grass.

The reason he was looking for this was simple. He could break through to reach the Martial Origin Stage anytime. But, the reason he was holding back was to raise his foundation to the limit.

Other than that, after a breakthrough, his cultivation would only be at the Pseudo Martial Origin Stage. Only after their Martial Spirit fuses with a material would he reach the First Layer of the Martial Origin Stage.
